Treximet in the Treatment of Chronic Migraine

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.

This study is being conducted to evaluate the hypothesis that use of Treximet in patients with chronic migraine, when used on a short term daily basis and as rescue for break through attacks, will reduce migraine frequency and impact.

Phase 4

Detailed Description:

One investigative center will enroll 40 subjects in the US.

At Visit 1, following informed consent, a medical, migraine, and medication history will be collected and a physical and neurological exam with vital signs will be performed. A 12-lead ECG will be completed. Eligible subjects will complete a 1-month Baseline Period and treat migraine with their current preferred treatment of choice. Throughout the study, subjects will complete daily Headache Diaries reporting headache severity and associated symptoms with use of study medication in each 30-day period.

At Visit 2, subjects continuing to meet eligibility criteria will be randomized 1:1 to Treximet or naproxen and provided with medication to treat daily for 30 days. At Visits 3 and 4 subjects will be provided with study medication to treat on 14 or fewer days per month. Subjects will be encouraged to treat their migraine attacks within 1 hour of onset of headache pain and while the pain is still mild. Adverse events will be collected beginning from the first dose of study medication. Subjects exit the study at Visit 5 after a 3-month Treatment Period.

The study provides opportunity to evaluate the usefulness of patient education with a 15-minute digital versatile disc (DVD) concerning the processes of headache evolution and lifestyle changes for better headache management. At Visit 2, subjects will view the DVD in-clinic with a copy provided for at-home viewing. Subjects will complete a Lifestyle Choices for Better Migraine Management Questionnaire at each visit and receive 3 copies to be completed weekly and returned at the following visit.

The Migraine Disability Assessment questionnaire (MIDAS) will be completed at Visits 2 and 5 to determine the level of pain and disability caused by headache.

In Treatment Period Month 1: Subjects randomized to Sumatriptan/Naproxen Sodium will treat daily with 1 tablet Sumatriptan 85mg / Naproxen Sodium 500mg per day x 30 days. Subjects will be provided with 30 tablets of Sumatriptan/Naproxen Sodium for rescue. In Treatment Period Months 2 and 3: Subjects randomized to Sumatriptan/Naproxen Sodium will be provided with 14 tablets of Sumatriptan/Naproxen Sodium to treat on 14 or fewer days per month. Subjects will be provided with 14 tablets of Sumatriptan/Naproxen Sodium per month for rescue.

Drug: Sumatriptan/Naproxen Sodium

Each tablet of Sumatriptan/Naproxen Sodium for oral administration contains sumatriptan 85mg / naproxen sodium 500mg. Study medication is to be administered 1 tablet per day x 30 days in Treatment Period Month 1. Study medication may be administered on up to 14 days per month in Treatment Period Months 2 and 3.

In Treatment Period Months 2 and 3: Subjects randomized to Naproxen Sodium will be provided with 14 tablets of Naproxen Sodium to treat on 14 or fewer days per month. Subjects will be provided with 14 tablets of Naproxen Sodium per month for rescue.

Drug: Naproxen Sodium

Each tablet of Naproxen Sodium for oral administration is provided in 500mg tablet. Study medication is to be administered 1 tablet per day x 30 days in Treatment Period Month 1. Study medication may be administered on up to 14 days per month in Treatment Period Months 2 and 3.

Percent Change of Migraine Headache Days Compared to Baseline [ Time Frame: Day 121 (following 30 day Baseline Period and Treatment Period days 91-120. ]

Comparing the number of migraine headache days during Baseline Period days 1-30 to number of migraine headache days reported in Treatment Period days 91-120 in the Sumatriptan/Naproxen Sodium arm versus (vs.) Naproxen Sodium arm. Percent change=[(total headache days during Treatment Period Month 3(days 91-120)-total headache days during Baseline(days 1-30)/total headache days during Baseline(days 1-30)]*100%)

Secondary Outcome Measures
:

Percent Change of Migraine Headache Days in All Treatment Periods Compared to Baseline [ Time Frame: Baseline Period (days 1-30) collected at Day 31, Treatment Period Months 1, 2, and 3 collected at Days 61, 91, and 121, respectively. ]

Comparing number of migraine headache days from Baseline to Treatment Period Months 1, 2, and 3 in the Sumatriptan/Naproxen Sodium arm vs. Naproxen Sodium arm.

Each treatment period month percent change was individually compared to Baseline. The following formula was used for each treatment period calculation.

e.g. percent change=[(total headache days during Treatment Period Month 3(days 91-120)-total headache days during Baseline(days 1-30)/total headache days during Baseline(days 1-30)]*100%)

Percent change was calculated by determining percent change in each subject, from each Treatment Period month compared to Baseline. The following formula was used for each treatment period month calculation.

Migraine Headache Duration From Time of Treatment to Pain Free [ Time Frame: Baseline Period collected at Day 31, Treatment Period Months 1, 2, and 3 collected at Days 61, 91, and 121 respectively. ]

Percent change was calculated by determining percent change in each subject, from each Treatment Period month compared to Baseline. The following formula was used for each treatment period month calculation.

e.g. Percent change=[(mean migraine duration from time of treatment to pain free during Treatment Period Month 3(days 91-120)-mean migraine duration from time of treatment to pain free during Baseline(days 1-30)/mean duration from time of treatment to pain free during Baseline(days 1-30)]*100%)
